Are you still out there? I am not having any luck with a SMMBlinkTextView simply added with the Designer. Should not have to do anything right?

I tried adding Reflection library, but to no avail. Also, the log is not happy at all: "Library 'BlinkTextViewWrapper' is not used. (warning #32)"

I just want to blink, man.

B4X:
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 20 (B4XMainPage)

This all works. vxAbort is just a dummy label added in the Desginer that is not enabled or visible.

B4X:
Dim Blink As SMMBlinkTextView
    Blink.Initialize("vxAbort")
    Dim b4xBlink As B4XView = Blink
    b4xBlink.SetLayoutAnimated(0, vxAbort.Left, vxAbort.Top, vxAbort.Width, vxAbort.Height)
    b4xBlink.SetColorAndBorder(0xFF7FFF00, 2dip, clrApp, 6dip)   '  the illusive ColorDrawable
    b4xBlink.SetTextAlignment("CENTER","CENTER")
    b4xBlink.TextColor = vxAbort.TextColor
    b4xBlink.TextSize = vxAbort.TextSize
    b4xBlink.Text = "A B O R T"
    Blink.AddToParent(xPage, vxAbort.Left, vxAbort.Top, vxAbort.Width, vxAbort.Height)
    Blink.BringToFront

Just blinking? Did you have a look at this very old lib of mine.?
If not for the lib itself, it could give you a simple hint on a standard Android component.

Shouldn't be that hard to create a B4X view, then you can add it in the designer and additionally in all IDE's of B4X.
If that's a solution for you, I'll do it quickly.
Thank you, Alexander. Doing something exactly like that is high on my "to learn" list.

I was mistakenly hung up for a bit thinking that events would not fire during a Sleep. Turned out that the click would not work when the view was briefly "off". Transparent label over the blinking thing fixed it.

I use so much of your stuff. If I ever make a dime on anything, I'll be hitting the Donate button.

Thank you, Alexander. Doing something exactly like that is high on my "to learn" list.
I had a short break earlier, so I did this quickly, since I'm not at home, I could only test the whole thing in B4J, later I'll publish it officially, but you can see if it works as well as the other library. :)

You can add this view with the designer or per code
B4X:
'Creates as view per code
Dim Blink As AS_BlinkTextView
Blink.Initialize(Me,"Blink")
Blink.AddToParent(Root,0,0,50dip,50dip)
Blink.Text = "Test"
Blink.Font = xui.CreateDefaultBoldFont(20)
Blink.TextColor = xui.Color_White
Blink.AnimationDuration = 250
Blink.StartBlink
